ZeroTier 1.6.0 is here. Download now.


Our mission is to directly connect the world’s devices and enable a new era of decentralized computing.

Our software automatically handles the complexities of networking across physical network boundaries, dealing with mobility, and unifying cloud and edge to free you to spend your time building your projects and running your business.

Our network virtualization technology delivers the power of enterprise software defined networking to every device, service, and application whether it’s located at the edge or in the cloud. With ZeroTier you can treat the entire planet like one data center or cloud region. It’s capable enough for large businesses with complex networking needs but easy enough that tens of thousands of regular people use it to do simple things like play games online or connect to their home PC from their mobile device.

Our software and SDKs help developers build distributed and decentralized applications that are both easier to create and pleasurable to use. We work to solve the hard technical problems underlying decentralized application development so you can deliver applications that offer a positive low-friction user experience while avoiding the cost, liability, and security/privacy impact of a large highly involved cloud presence.

ZeroTier is located in Irvine, California and was founded by Adam Ierymenko in 2015.
